Technical Field

the invention discloses a preparation method of a tar viscosity reducer for reducing tar viscosity. The invention is applied to the coking industry, and the viscosity of tar can be reduced at normal temperature by adding the invention into the tar, thereby achieving the functions of convenient transportation and reducing danger.

Background

In the existing coking industry, there is a great inconvenience in the transportation of tar. The tar is viscous black liquid at normal temperature, has a flash point of about 80-90 ℃, and belongs to flammable liquid. The viscosity of tar decreases with the increase of temperature, but the steam and air can form explosive mixture at high temperature, and the tar is easy to burn and explode when exposed to open fire and high heat. Contact with oxidant and react violently. If high heat is encountered, the internal pressure of the container is increased, and the danger of cracking and explosion is caused.

The invention can reduce the viscosity of tar and enhance the fluidity of tar at normal temperature, and is more beneficial to the transportation of tar. In addition, the viscosity of tar is reduced at normal temperature, the consumption of steam is reduced, the fluidity of the tar is not maintained at high temperature, the energy consumption is greatly reduced, the cost is reduced, and the economic benefit of a company is increased.

According to the existing conditions, the invention discloses a preparation method of a tar viscosity reducer for reducing the viscosity of tar, aiming at reducing the viscosity of the tar, keeping the tar in a liquidity state at normal temperature, and reducing the cost in the transportation process and the danger at high temperature.

The surface active agent can reduce the viscosity, has less dosage of the surface active agent, convenient operation, no toxicity and no corrosion, and is an ideal chemical product, thereby having important application in factories and scientific research. When the concentration is the same, the non-polar component in the surfactant is large, and the surfactant has strong surface activity. That is, among the homologs, the surface activity is large when the number of carbon atoms is large. However, if the carbon chain is too long, the solubility in water is too low, and thus the carbon chain is of no practical value.
